10–80%min
10-80% time is the common fast-charge stop duration from a low road-trip state to a useful high state. It matters because charging decides how the car fits your week and how tiring long trips become. Home AC charging, public DC charging and the charge curve answer different questions.
How to compare it
Compare it with range added, not just minutes. A 20-minute stop is better if it adds enough real motorway kilometres.
- Separate AC home charging from DC fast charging.
- Use 10-80% time and average power for road trips.
- Remember that battery temperature can change the result.
What changes it
Charging results move with charger capability, battery temperature, starting state of charge, pack voltage and how aggressively the car protects the cells.
- A warm battery usually charges better than a cold one.
- The useful window is normally 10-80%, not 0-100%.
- The lowest limit wins: car, charger, cable, grid or temperature.
Common trap
Charging above 80% usually slows down, so road trips often work better with more shorter stops than one long 100% stop.
- Peak kW is not the whole session.
- The charger rating does not guarantee the car will accept that power.
10–80%: what happens during a charge stop
Charging is a curve, not a single peak. The average over the useful window is what shortens a trip.
